Description

Module13.2 Stepmotor Driver v1.1 is a stepper-motor driver designed for M5 controllers, adopting an STM32 + HR8825 solution and providing three bipolar stepper-motor control ports. After stacking with an M5 controller, the on-board ESP32 directly generates signals for the driver IC, allowing either independent axis control or multi-axis linkage. An integrated STM32F030F4P6 acts as an IO expander, offering four input signal terminals and one driver-enable control, enabling I2C communication to control and monitor the driver’s reset and status, suitable for external limit switches and motor brake functions. Three solder pads on the module set the micro-stepping modes for the three motors. A built-in PWR485 communication port (RS485 + 9-24 V power input) and a DC-JACK provide flexible power options while communicating. UIFlow graphical programming is supported for easy signal configuration and precise stepper-motor control. The module fits various motion-control scenarios such as printers and robotic arms.
